Ultra-Flat capacitor replaces arrays of SMT capacitors

Distribution of a new Ultra-Low-Profile Aluminium Electrolytic Capacitor from Cornell Dubilier Electronics (CDE) has been announced by New Yorker Electronics. It is designed for bulk capacitance and the lowest board profiles.

Circuit designers can use a single component, saving space, weight and cost while improving dependability.

Energy density of over 0.4 J/cc enables the use of a single component instead of an entire array of SMT capacitors. This improves circuit reliability while achieving high capacitance on the board.

Due to its light weight, the ULP is ideal for use in portable devices and is well-suited for a wide range of applications where height profile, board space, weight and reliability are critical design factors. The ULP is offered in package heights of 2.2 and 3.2mm. Capacitance values range from 500µF to 24,000µF.

Working voltages range from 4 to 63 WVDC with an operating life of 3,000 hours @ 85°C.

Unlike solid tantalum capacitors, type ULP capacitors do not require voltage derating.

Housed in a highly durable nickel-silver case, the low-profile capacitor is rated at 10g for vibration withstand. As thin as 2.2mm, the ULP Series capacitors are easy to design-in.

With flat ribbon-lead style terminations, it is even possible to mount the device off-board -- providing added design flexibility in order to maximise available space.

Developed by Cornell Dubilier and distributed worldwide by New Yorker Electronics, the ULP breaks away from the cylindrical designs usually associated with aluminium electrolytic capacitors. The design is an outgrowth of the company’s over 20 years of experience in the manufacture of aerospace-grade flat capacitors.

Features include a high energy density of .4 J/cc and the ability to replace banks of solid tantalum chips. The device has REACH Compliant Fuse protection.

Applications include bulk storage in portable devices, disk drives, portable instruments and medical monitors, IoT remote monitoring devices, compact power supplies, drones and RPVs and video monitors, displays.
